Interesting setup. I thought you had mistyped the map dimensions till I did some black-clicking. One of the GOTMs in the 20's was a "RingWorld"; this one reminds me of one of those O'Neill cylinders from "Colonies in Space".
OCC Report (from black-clicking): The starting position is one tile west from a 3Special location; unfortunately it is landlocked, and then there are the forests. The 4Special spot to the southeast is Ocean, but the one due east is on land with access to Ocean. There is also one westward that is on a neck of land with Ocean on two sides. Further out is harder to tell as the island seems odd-shaped with a few smaller ones nearby.
Because we only have the one hut to work from we cannot tell the Special pattern until we find at least one visible Special. There are two possible Resource Seeds that fit the visible starting setup, #'s 2 and 34. #2 puts us in a band of all-Whales, which would be very nice as they give good high-trade terrain (Silk, Wine, Spice, Furs). #34 is half Whales, half Fish on opposite corners. If the Forest continues northeastward there should be either a Silk or a Pheasant just beyond that which is visible.
In either case, both 4Specials have two specials on land and two at sea. If the Resource Seed is 34, eastward has one Whale and one Fish and one of each type on land; westward has two Whale and two Fish-type on land. Higher trade specials on land are better, since you can Road them to get an extra trade arrow and then SuperHighways will give 50% more trade.
On such a large map it is unlikely we have neighbors on our island, but our island is not small so there is a possibility. Before planting your first city the chance of getting a mercenary unit is 60%, gold and tech are both 20%. Settling quickly is a priority when you only have one Settler.
